STERILIZER.

Application tiled March 2', 1926. Serial No. 91,833.

This invention relates to improvements in sterilizers, and hasparticular reference to a sterilizer for use in the cleansing of bottlessuch as nursing bottles, fruit and the like.

Another object of this invention produce a device of this character in aplurality of bottles may be placed, sterilized and removed from thesterilizimgk liquid without injury Vto the person using the same.

Another object is to produce a device of this nat-ure which is cheap tomanufacure, and therefore well within the purchase price of the averageuser.

A still further object is to provide means whereby a plurality ofnipples may be also sterilized at the same time.

Other objects and advantages will be apparentduring the course of thefollowing description.

In the accompanying drawings forming a part of this invention, and inwhich like numerals are used to designate like parts throughout thesame,

Figure I is a vertical cross-section showing my device in use as thesame would ap.- pear when sterilizing the contents of the bottle,

Figure II is a top plan view ofthe retaining plate, l

Figure III is a top plan view of the bottle rack, and

Figure IV is a view similar to Figure I showing the bottle and rack inan invert-ed position so as to sterilize the interior of the bottles.

At the present time, in the preparing of formula milk, it isV firstnecessary to thoroughly cleanse the bottles by immersion in boilingwater, then the bottles must be removed, drained, cooled and filled withthe milk, after which the bottles are again placed in a vesselcontaining water, heated to a predetermined temperature, and thenQuickly cooled in order to Pasteurize-the is to which Y milk within thebottles.

The sterilizing of the bottles in an Ordinary vessel requires time inplacing the bottles in the vessel, with the danger of burning the handswhen removing the bottles from the water, also in sterilizing thenipples the same float upon the surface oftentimes, and are thereforenot properly sterilized, and when they drop to the bottom of the vesselthey are extremely difficult to extract from the water, besides beingditicult to locate. Y

I have therefore provided a bottle holding rack which will obviateall ofthe above di'liiculties and disadvantages. f Inthe accompanying drawingswherein for the purpose of' illustration is shown a preferred embodimentof my invention, the numeral 5 designates a vessel, within which I placea rack constructed with a plurality of tip-rights 6. This rack ispreferably formed of wire. These uprights 6 are con- .n'ected to a ringT, which ring is in turn provided with a bail 8. The bottom of the rackis formed with a plurality of spokelike T members 9 which oin theuprights 6.

At 11 and 12 I have shown vertically dirposed wires which are connectedto a ring 13. Between these wires 11 land 12 I position a receptacle 14within which nipples must be placed after which a screen cover 16 issecured to a wire ring 13.

At 17, I have shown a retaining plate having ears 18 and 19 which areadapted to engage the ring 7, while at 2l I have prof vided a springcatch which is also adapted to engage the ring This retaining plate 17is provided with a plurality of openings 22 through which the necks ofthe bottles to lbe sterilized may pass.

The manner of using my device is as follows Assuming that the rack is inthe position shown in Figure I, the retaining plate 17 is removed, thebottles are placed within the rack and the retaining plate replaced.

The bottles are now filled with water and the receptacle 5 is alsopartially filled with Water. By now quickly inverting the entire rackand dropping the same into the vessel 5 the water will be retained inthe bottles and the rack and the bottles will assume the position shownin Figure IV. After the water has reached a boiling point, the ent-irerack may be lifted out of the' vessel by employing a hook 23 andengaging one of the with the formula milk and the necks plugged withCotton. The rack may now be reinserted in the vessel and the watergradually brought up to tlre desiredv degree of heet.

It will thus be seen that by employing` my rack it is not necessarytotoueh the bottles filter they have once been placedin the rack. Afterthe milk has been Pasteurized the entire rack may be removed from partsniziy be resorted to without departing?v from the spirit of theinvention or the scope ol the subjoined claim.

Having thus described my invention, I claim: A 1

Irl ai device ofthe Character described, :t plurality of verticallydisposed' members, a ring secured to the upper extremity of saidvertically disposed members, e plurality or' spoke-like members'connecting to the lower extremity `of said vertically `disposed members,said spoke-like members converging and joining at a centrelpoint7uprights secured to said spolrelilre members, e? .ring secured to saidlast mentioned. uprb screenremovwbly secured to said lust men-- tionedring, as and for the purpose .de scribed. y l A y In testimonyWhereoiieix my signetuic.
